The feasibility of using EDXRF for a rapid quantitative analysis of gold in tumor tissue has been investigated. The protocol described here demonstrates that sample biopsies can be analyzed in as little as 8 hours, with minimal sample preparation. Samples were prepared by drying a 35 μL aliquot of tissue dissolved in KOH in a standard EDXRF cup on a Prolene® support, producing a thin sample. Calibration curves of XRF peak intensity (cps per mA) to the gold concentration (0–50 ppm) were prepared for liver, tumor, and a mix of tissue types. A linear regression demonstrated an R2 correlation of 0.93. Analysis of experimental samples showed that gold accumulation in tumors (5.8–41.3 ppm) was in agreement with previous studies, where samples were processed using INAA or ICP-MS. This report provides guidance for elemental analysis of gold in tissue in a shorter time span, showing potential for its use in a clinical setting.
